keyed_groups

list / elements=string

Add hosts to group based on the values of a variable.

Default: []

leading_separator

boolean

added in 2.11 of ansible.builtin

Use in conjunction with keyed_groups.

By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.

This is because the default prefix is “” and the default separator is “_”.

Set this option to False to omit the leading underscore (or other separator) if no prefix is given.

If the group name is derived from a mapping the separator is still used to concatenate the items.

To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.

Choices:

  • no

  • yes ← (default)

ports

boolean

Enable/disable scanning for open ports

Choices:

  • no

  • yes ← (default)

strict

boolean

If yes make invalid entries a fatal error, otherwise skip and continue.

Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

Choices:

  • no ← (default)

  • yes

use_extra_vars

added in 2.11 of ansible.builtin

Merge extra vars into the available variables for composition (highest precedence).
